Molecular biology is the study of biology at a molecular level.The field overlaps with other areas ofbiology and chemistry, particularly genetics and biochemistry.Molecular biology is a science chiefly concerned with understanding the interactions between the various systems of a cell, including the interrelationship of DNA, RNA and protein synthesis and learning how these interactions are regulated.The most basic technique used by a molecular biologist to study protein synthesis is expression cloning. Rapid developments are taking place in all sub-disciplines of the Molecular Biosciences, including cell biology and biotechnology.this is coupled with huge progress in the analysis of the base sequence of genomes of various organisms,including the human organism.The database of high-resolution protein structures is also rapidly being expanded.
All this has increased the scope of this field manifold.Research in this field is quite challenging as one has to gain insight into the molecular interactions between all the components of a cell. Researchers in the fields of bioinformatics, biophysics and physics, chemistry, (molecular) biology and physiology work together closely to develop new strategies and techniques.Molecular biology is basically a research field. Hence, entry in this field is generally after doctoral degree. A student after completing 10+2 can take up a bachelor’s course in molecular biology or an allied field like biotechnology, genetic engineering. Admission to B.Sc is done primarily on the basis of merit in H.S.C. after this one can pursue M.Sc in an allied field and then go for Ph.D. this can be followed by one or two three-year stints as a postdoc in other laboratories.
You do have to be able to understand the logic behind previous experiments and use it to design your own and a reasonable grasp of basic maths, chemistry, and biology is important. Beyond that, perseverance, commitment, and common sense are what’s needed to succeed.There are opportunities for scientists with degrees or postgraduate training in many areas—in the pharmaceutical industry, in the media, as government advisors, in patenting and scientific consultancy, and in scientific writing or editing.
